    "title": "NHSN SAFR Data Aggregator CapabilityStatement",
    "description": "This statement defines the expected capabilities of a system that aggregates data from multiple Data Source actors before measure evaluation and then plays the role of a Data Source once aggregation is complete. An example would be a state public health agency aggregating data from all facilities in the state before using those data to produce a MeasureReport containing bed capacity data for the entire state. When FHIR enabled, a Data Aggregator acts as a [US Core Server](http://hl7.org/fhir/us/core/STU6.1/CapabilityStatement-us-core-server.html) when playing the role of a Data Source after aggregation. During aggregation, the Data Aggregator acts similar to the SANER options for aggregation, but implements its own CapabilityStatement due to the incompatibilities between DEQM and SANER.",
